In the final week of semester (first week of exams) I had tested the facial recognition technology aspect of ZipperBan. It comprises of a Flash movie that:
- asks to register your face as the owner, and enter a name
- in registering your face, it takes 5 photos in order for the Eigenface method to work properly
- It is also connected to my second interactive prototype with the makey makey, and so prompts the user to begin unzipping the bag
- unzipping the bag triggers the camera to take a snapshot of the user, and after comparing with the face of the owner, either states “ACCESS GRANTED” or “THIEF ALERT”
The final interface can be seen below:
The testing session was also successful in testing the efficacy of the facial recognition system and testing it with different lighting settings and different people. Overall people seemed to enjoy using the facial recognition technology, and more often than not it would detect correctly if the person was the registered owner of not.
The testing process occurred as follows:
- the subject sat down and was briefed on the concept of the prototype
- they followed the prompts - first by entering their name
- they then took 5 photos of their face for training and went on to unzip the bag
- the console printed out that the person identified in the photo is indeed the registered owner
- after the system guesses the owner correctly, I then try to unzip the bag to test if the opposite is true, and surely enough, it recognises that it is me and outputs ‘THIEF ALERT’
Some other feedback received was to transfer the information being received in the console onto the actual prototype itself, so the user could see what is happening at every step.
